There are some pretty repellent people preparing to stand at the election: and, in time, we shall come on to the question of the Hon Dr Tristram Hunt, who seeks to become the people's party's representative for Stoke. For the moment, however, there is one urgent priority: and that concerns the man whom it shames Britain to have to call the Speaker of the House of Commons, John Bercow.

The disgusting spectacle of this saponaceous little creep shaking hands with various expenses fiddlers as they left the House of Commons on Thursday, of his boasting that (since being rumbled for a bit of taxpayer-funded extravagance himself) he has in fact been very cheap to run, and of his gall in using the Leader of the Opposition (who, I would wager, cannot stand the sight of him) to endorse him on his website, is of a piece with the atrocious behaviour that led him to occupy the Chair in the first place. The Speakership should be an act of public service: but for Little Bercow it is simply an act of ambition.

His own party cannot stand him. The Labour party, outrageously choosing to score a political point in the aftermath of the expenses scandal, rather than to salvage the reputation of the House of Commons, thought it was frightfully funny to elect him to his post. He has neither the experience nor the gravitas to do the job properly. As he sat in his Mothercare-supplied robes, presiding over the most corrupt House of Commons for centuries, looking like a man waiting for a spot on a toadstool by an ornamental pond to become vacant, one could conclude that he and they deserved each other. But we, the electorate, have done nothing to deserve him.

Since he is notionally a Conservative, that party has no candidate against him. Nor do the Lib Dems or Labour, and they would look foolish if they did: after all, they wanted him to be Speaker in the first place. There are (so far) various independents, and a bonehead from the BNP. But there are two serious candidates: Nigel Farage, the charismatic former leader of Ukip, and John Stevens, a former MEP standing on a "democracy" ticket. I have nothing against Mr Stevens, but his politics are too bland for me. I am in no doubt that the people of Buckingham, not least to perform the public service of removing the smear of Bercow from British politics, should vote for Mr Farage.

After all, as well as his election's providing that happy outcome, there would be other bonuses: which is that Buckingham would again have a proper conservative MP. Mr Farage is most notably standing on a programme of getting out of Europe, which the Tory party itself will soon have to own up to as the only alternative to the status quo – nobody is going to let them renegotiate anything. However, he also believes in many other things that real conservatives want and that Dave won't give them: serious public spending cuts, the reduction in the size of the state, grammar schools, strict immigration controls, and a commitment to making questions such as smoking in pubs and hunting with hounds matters of personal liberty.

Any conservative living in Buckingham should vote for Mr Farage. So should any Conservative, given they have no candidate. But so, indeed, should anyone who cares about the institution of parliament. Bercow has shown he has no place there. Those who recall Mr Farage's splendid assault on Herman van Rompuy in the European Parliament a few months ago will know he has the courage of his convictions. He now has another nonentity in his sights: I do hope he is given the means to pull the trigger.
